The DISTINCTION of baptism
It is instantaneous, happening at salvation
Every believer is baptized by the Spirit (1 Cor. 12:13)
The church at Corinth was filled with some very carnal believers but were all baptized by one Spirit
This can only be the case if it happens at the moment of salvation
The aorist tense would show that this is a one-time action that is not repeated
Ephesians 4:5 - One Lord, One faith; One baptism
Nowhere are we commanded to seek the baptism of the Holy Spirit (though we are commanded to be filled with the Spirit – Ephesians 5:18)
